Maria’s father started a fire in the fireplace. He crumpled some paper, lit a match, and soon the logs in the fireplace were burning. In the case, the stored chemical energy in the logs was changed into

The options are

A) electrical energy.

B) mechanical motion.

C) heat and light energy.

D) electrical and heat energy.

The answer is C) heat and light energy.

Explanation:

Chemical energy in the wood is lit up by fire and a burning process begins to occur. Burning involves a substance being consumed by fire and fire aids in the conversion of some forms of energy to mainly light energy as a result of the burning flames and also to heat energy as a result of the high temperature in the form of heat which the fire brings into play.

This validates the stored chemical energy in the logs being changed into light and heat energy.

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
